The lift and other settings is this for the entire server or Per User ?
If its for the whole server can you make a custom one for per user so they can select their own options ?

It wouldn't be wise to have a user select these settings, as it could basically give them speed hacking capabilities.

on a build server they are admins using Fauxadmin

@tomhud I have a couple of features planned for the next couple of weeks, once that's implemented I will look into this. 

For the time being, if you can explain how this would be best implemented, which features should be changeable? And how should they be changed from a UI perspective, as I am not familiar with build servers. 

This will probably just be a seperate plugin for this, for simplicity. 

when they go to spawn the heli a small GUI will show up and allow them to set the Lift Fraction /Pitch/ROll and Yaw
they can either go with default and hit spawn Mini at the bottom of the GUI or they can change the 4 options with their own settings (within reason so will have to have a min and max for each settings)
